Effects of Subsetting by Carbon Content, Soil Order, and Spectral Classification on Prediction of Soil Total Carbon with Diffuse Reflectance Spectroscopy

Figure 2

Average (a) visible/near-infrared (VNIR) and (b) mid-infrared (MIR) diffuse reflectance spectra of soil groups used in subsetting by soil order. Dashed lines represent one standard deviation from the average.
